Name: Water Softener Filter System
Brand: HZM Machinery

Brief Introduction

The water softener removes calcium and magnesium hardness through ion exchange. This reduces scale formation in downstream piping, heat exchangers and reverse-osmosis equipment. The resin is regenerated with brine so that the system can return to its softening cycle.

Product Features

Working Principle

Cation exchange resin is filled in the softener, and it is regenerated by running in the downstream and countercurrent. When the filtered water enters the softener, Ca2+and Mg2+ions in the water will exchange with the cation exchange resin, and calcium and magnesium ions will be adsorbed on the exchange group.When the softened resin fails, a certain concentration of salt solution is used to pass through the failed cation resin layer from top to bottom to restore the working capacity of the failed resin.

Working Process

Product Water

Untreated raw water flows through the resin layer from top to bottom, and ion exchange reaction takes place to produce softened water, which is discharged from the soft nozzle.

Back Wash

After the resin fails, it needs to backwash first. Raw water flows through the resin layer from bottom to top, and backwash sewage is discharged from the drain outlet. The backwashing process can remove the suspended solids trapped in the resin layer, destroy the resin hardening, and loosen the resin so that the regenerated salt solution can be evenly distributed in the resin layer.

Regenerate

The saturated salt water in the salt tank is sucked into the raw water runoff by the salt suction valve to form the regenerated salt solution. Regenerated salt solution flows through the resin layer from bottom to top, that is, the exchange saturated resin is regenerated in the downstream, and the regenerated waste liquid is discharged from the drain outlet.

Rinsing

The raw water flows through the resin layer from top to bottom, so that the water can wash away the surplus salt liquid remaining in the regeneration, and the flushing sewage is discharged from the drain outlet.

Water Flooding

Inject water into the dissolved salt tank to dissolve salt crystals and form new saturated salt water for reuse next time.

Resin Replacement

If the regeneration frequency of the softener is too high or the hardness of the effluent cannot meet the requirements after regeneration, the softened resin has failed, and the softened resin needs to be replaced. The failure period of softened resin varies according to the hardness of raw water and the use frequency of softener, generally 2-3 years.

Frequently Asked Questions

What information is required to design this water treatment system?

Please provide a recent raw-water analysis, required treated-water standard, hourly demand, operating hours, available utilities and installation space. HZM uses these data to select pretreatment, membrane or polishing stages.

Why is a raw-water analysis required before equipment selection?

Source-water hardness, salinity, turbidity, iron, manganese, microbiology and other parameters determine the process route. Selecting equipment without these data can lead to unstable water quality, low recovery or unnecessary operating cost.

Can the system be expanded or adapted if the water source changes?

Expansion or process changes may be possible, but the new feed-water analysis and demand must be reviewed. Tanks, pumps, membranes, pretreatment capacity, controls and available space determine what can be reused.

Can this equipment be integrated into a complete production line?

Yes. HZM can coordinate upstream processing or bottle making with filling, labeling, coding, packaging, conveying and palletizing. Layout, utilities, controls, factory testing, installation, commissioning and training are defined by the agreed project scope.
